Improve Your Wireguard Server's Performance
The default MTU(Maximum Transmission Unit) is 1420 in wireguard, while the most other devices use 1496 or 1500.
Read here for more info.
Stop the wireguard interface in use:
1sudo systemctl stop [email protected] 2# or 3sudo wg-quick down wg0
Edit the wireguard config file:
1sudo vim /etc/wireguard/wg0.conf
MTU=1400 to the
Interface section like this:
1[Interface] 2Address = 10.10.10.1/24 3SaveConfig = true 4ListenPort = 51820 5MTU = 1400 6PrivateKey = xxxxxx
And start the stopped service:
1systemctl start [email protected]
Add the same for the client config.
Hope this helps.
